Abstract
An AMR array magnetic position sensing method and system for improving sensor-to-magnet carrier misposition. A magnetic carrier can be provided, which maintains two or more magnets with angled magnetic vectors position above an array of AMR array sensors. The magnet carrier can then be passed over the AMR array sensors to generate an output signal having less susceptibility to variations in air gap because the angles of flux lines generated by the magnets do not change much with air gap variation. The AMR array sensors are generally sensitive to variation in a direction being sensed, because a constant magnetic field angle sensed by AMR runners located on the AMR array sensors do not change with respect to variation in other directions.
